Advice: OTA < 33 lbs for DSO Visuals

[Gizmo]

Hello,

I have a mount (iOptron AZ Mount Pro) that can take an OTA of up to 33lbs.

I was hoping if you could share you knowledge with me.

What OTA would provide the best visual (not interested in AP) performance for Nebulae, Clusters and Galaxies that does now weight more than 33lbs.

Thanks in advance for your advice.

I'd guess at an 8" F/5 newtonian

there's a celestron C9.25 in the classifieds here, id grab that -about 22lbs I think

a cAT will sit much easier on that mount than a longer tube NEWT, I don't think id be sticking 15kg on it in any case

Thanks for the advice.
I've had a celestron before but was unlucky enough to get one with the haze issue
Also being F10 I'm thinking something faster would be better for DSO?

Any other kind person got some advice at other good options out there?

For visual the focal ratio isn't really important. A 8" F/5 with a 10mm eye piece will throw up exactly the same view as a 8" F/10 with a 20mm eye piece.
Focal ratio is more important for photography

A C11 is under 33lbs...modern versions are around 12-13kg.

There is a C11 in classifieds that looks good. Cheers Richard
